- (void)connection:(NSURLConnection *)connection   
   didSendBodyData:(NSInteger)bytesWritten
 totalBytesWritten:(NSInteger)totalBytesWritten
totalBytesExpectedToWrite:(NSInteger)totalBytesExpectedToWrite    {

    float progress = [[NSNumber numberWithInteger:totalBytesWritten] floatValue];
    float total = [[NSNumber numberWithInteger: totalBytesExpectedToWrite] floatValue];
    NSLog(@"progress/total %f",progress/total);

Please Improve You Question. What i understand form it here is the base Idea.

Upload File On Server

So please review this answer for idea of uploading an file on server
Show ProgressView

First You need to add progressView in UI Thread and then create another thread for communicating with server that thread will responsible for uploading file and with base idea callback as response from server with in UI Thread and remove progressView.

like review this code

dispatch_queue_t anotherThreadQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_LOW, 0);
//add progress view here...
dispatch_async(anotherThreadQueue, ^{
        //then upload file here....
dispatch_async(dispatch_get_main_queue(), ^{
            // UI Thread update View ( remove progressView)
      });
 });

or for showing the progress for uploading file you can use connection:didSendBodyData:totalBytesWritten:totalBytesExpectedToWrite: as you using NSURLConnection

i completed uploading file on server, if i implement didSendBodyData for NSURLConnection, its not called properly? – Velu Loganathan Jun 24 '14 at 11:55
`didSendBodyData` called when the request has a body data like in `POST`. are you using `GET` ? – Buntylm Jun 24 '14 at 12:00
as the process says we can track the uploading process using `didSendBodyData` now you need to track on your side as `delegates` or minor issue will be there. – Buntylm Jun 24 '14 at 12:11
i m using NSURLConnectionDelegate in .h ? is that fine? – Velu Loganathan Jun 24 '14 at 12:13
tried that too but no effect on **didSendBodyData** – Velu Loganathan Jun 24 '14 at 12:22
`NSURLConnection *conenction = [NSURLConnection connectionWithRequest:request delegate:self];` and ensure `< NSURLConnectionDataDelegate >` – Buntylm Jun 24 '14 at 12:26
yes already done those things, But still no effect on delegate – Velu Loganathan Jun 25 '14 at 05:54
Finally i got it :) this post helped me http://stackoverflow.com/questions/5787170/nsurlconnection-delegate-methods-are-not-called – Velu Loganathan Jun 25 '14 at 09:21
so what was the problem ? – Buntylm Jun 25 '14 at 11:45
i missed to set [connection start]; – Velu Loganathan Jun 26 '14 at 05:25
Oh :) happen sometime... BTW good luck and for good programming habit review your code line by line. – Buntylm Jun 26 '14 at 05:42
